Abstract

The basic principle of X-ray fluorescence analysis for the determination of impurity elements Mn, Fe and Ni in copper alloy is introduced. On the basis of experiments, through theoretical analysis and experimental data, the variation trends of characteristic peak area and peak back ratio of Mn, Fe and Ni elements with the change of light tube current and tube voltage are obtained, so as to establish the best working condition mode of different elements. The relative standard deviations of Mn, Fe and Ni are 0.65%, 0.05% and 0.18% respectively. Multivariate regression analysis in the empirical coefficient method was used to establish a mathematical model to correct the matrix effect of Mn, Fe, and Ni elements. The experimental results show that the average absolute errors of Mn, Fe, and Ni content in copper alloys analyzed by the empirical coefficient method are 0.001%, 0.034%, and 0.002%, respectively, and the average relative errors are 0.698%, 2.205%, and 0.110% respectively.
